Pies Posted October 10, 2006 Report Share Posted October 10, 2006 AP902 maxed out. Skimming well, mainly dry although I empty about half AP902 collection cup weekly. Should I be skimming wetter? Thats pretty much the same as me, about 3/4 a cup a week, but I probably have twice the water volume and a lot more fish than you. Our systems are very similar (skimmer, light, coral, fish load per volume, ca reactor) so i'll tell you what I do. I have the CA reactor running 24/7. I top-up freshwater with kalk (sometimes) every night. Other than that I feed several times most days, never on other days. Otherwise thats it. I have lights on for 12hrs a day, lots of water movement. I have sand (tick tick tick) and lots of rock. Pie Quote Link to comment Share on other sites More sharing options...
puttputt Posted October 10, 2006 Report Share Posted October 10, 2006 I get 5 litres a week from my 902. I skim pretty wet but it's still pretty dark muck that comes out. Again my system is almost the same as yours Pies, but I don't feed as much, and skim more (wetter??). Light, calcium reactor, photo period, etc the same, and very similar to Chims. Use ASW though, BB, and lots of rock. Quote Link to comment Share on other sites More sharing options...
cookie extreme Posted October 10, 2006 Report Share Posted October 10, 2006 come pick it up i will see you on the weekend . joke aside. it seems by looking at the first picture (acro.) that growth has ceased almost completly. why would be the question. are you coral's starving? or using all their energy (the little thats left to block harmful UV? until they reach the point when they just RTN. now some people on this forum would argue that a tank will contain "enough" food, which is something i don't agree with (after seeing "snowstorms" of particles with incoming tides just recently in fiji). i also believe that corals once established are quite hardy and take a while before they die so it be more then one factor which causes your problems, and not just one "easy fix solution". the recovery if possible would also take some time. i reckon that you "fried" your corals with that lighting upgrade and would say its the main culprit (not necessary the only one), but couple that with low food availability, nice clear strong flowing water and perhaps being low with certain trace elements (but looking at the amount of water you have been changing lately i doubt that anything is ultra low to cause problems) good luck, as it will be a hard choice what to do next. (easiest is to go back to the same setup 6 month ago and see what happends) ripping out rock for more flow will most likely not do any good, more the opposite it will create even more stress. if you want to save small frags i will be more than happy to keep them for you for a while (no rent charged ) chris Quote Link to comment Share on other sites More sharing options...
chimera Posted October 10, 2006 Report Share Posted October 10, 2006 it seems by looking at the first picture (acro.) that growth has ceased almost completly. why would be the question. are you coral's starving? or using all their energy (the little thats left to block harmful UV? until they reach the point when they just RTN. possibly UV - extra flow through carbon combined with lighting upgrade may have caused it. but why would acro's sitting lower down in the tank have the problem and some near the top dont? ok, i know some acro's have different requirements than others, but there are some frags from the same colony in high and low areas. now some people on this forum would argue that a tank will contain "enough" food, which is something i don't agree with (after seeing "snowstorms" of particles with incoming tides just recently in fiji). agreed, so I've been feeding cyclopeeze and phytoplankton regularly (as well as the fluid from frozen foods). i also believe that corals once established are quite hardy and take a while before they die so it be more then one factor which causes your problems, and not just one "easy fix solution". the recovery if possible would also take some time. agreed i reckon that you "fried" your corals with that lighting upgrade and would say its the main culprit (not necessary the only one), possibly, but most definately not the only reason. there are many acro's that are just fine under that lighting and have been in there with the ones that are getting RTN. but couple that with low food availability nope. nice clear strong flowing water and perhaps being low with certain trace elements (but looking at the amount of water you have been changing lately i doubt that anything is ultra low to cause problems) yup good luck, as it will be a hard choice what to do next. (easiest is to go back to the same setup 6 month ago and see what happends) cher ripping out rock for more flow will most likely not do any good, more the opposite it will create even more stress. maybe, depends on what the issue actually is if you want to save small frags i will be more than happy to keep them for you for a while (no rent charged) Quote Link to comment Share on other sites More sharing options...
